Adventures in Virtual Fashion Design: Creating a Simple Men’s T-Shirt

Well, today I spent quite a few hours trying to make a “simple” men’s T-shirt, and learning from my mistakes along the way. My first design had the sleeves as part of the T-shirt body itself, and it looked like this:

But when I wore it in-world, I would get holes where my upper arms poked through, and no amount of adjusting the fabric in Lookbook would fix the problem.

I reported the problem to the Fashion channel on the official Sansar Discord server, and one person said:

I think it’s all because of big (very free) underarm region. When you simulate it in Sansar, it gets weights from body AND arms, and that region goes crazy…So basically it glitches because of extra room.

So I gave up on that design and looked around for a T-shirt pattern with separate pieces for the sleeves. I found this very useful tutorial on YouTube, and I followed it:

And I solved my underarm problem! But then I came across another problem. My T-shirt looked fine in the Marvelous Designer preview window:

But when I wore it in Sansar, I got these ugly silvery seams everywhere!

Again, I appealed for help on the Fashion channel, and I searched for and found something that Agustine had recommended as a way to get rid of seams: Disable the Show Internal Lines feature in the 3-D avatar display.
